Voting:Are you practicing myopia management ?
A. I do regularly
B. Rare or very rare
C. I don’t
D. What is myopia management ?
• Controlled application of preventive actions
for sustainable inhibition of bulbus axial
growth for the purpose of pathological
complications reduction.
• Kontrollierte Anwendung präventiver
Massnahmen zur nachhaltigen Hemmung
des Längenwachstums des Auges zwecks
Minimierung krankhafter Folgeschäden.
Global Epidemiology
Clinical Evidence
• Myopic Macular Degeneration
• Ablatio Retinae
• Cataract
• Glaucoma

„Currently, myopia maculopathy is the leading
cause of blindness in Taiwan, Japan and China.“

Causality
M u l t i f a c t o r i a lMany theories, often controversial results !
• Genetics (Wu und Edwards 1999, Morgan und Rose 2005, Foster und Jiang 2014)
• Environment / Dopamin (Feldkämper und Schäffel 2003, Jones et al 2007, Rose
und Morgan 2008, Pan, Chen et al. 2015, Xiong et al 2017)
• Emmetropization (Xiang et al 2012, Zadnik et al 2015)
• Close work / Digitalization (McBrian et al 1993 (-), Lin et al 2004, Mutti und
Zadnik 2009 (-), Wojciechowski 2011 (+), Mirshahi et al 2014 (+), Huang et al 2016 (-) )
• Accomodative lag /Esophoria (Gwiazda et al 2004 (-), Cheng et al 2014 (+),
Huang et al 2016 (-) )
• Peripheral Defocus(Smith et al 2005/2013, Atchinson et al 2005, Cagnolati et al 2011)
Myopiaprogression by AgeSankaridurg und Holden: Eye 2014
TherapySTOP !?
„In most of our participants, Axial Lenght (AL) increases rapidly at younger ages
and then slowed down and stabilized.“
Hou W. et al (COMET Group). Eye & Contact Lens: July 2018; Vol. 44/4, p.248-59
Actually most used and studied therapies
• Outdoor time
(Planned and advertised, Digital Devices)
• Eye glasses
(prismatisch, bi-/multifokal, PDF, DIMS)
• Contact lenses
(bi-/multifokal, PDF, Ortho-Keratology)
• Pharmaceuticals
(Atropine LAMP, Pirenzepin)
Update 2019
• Extensive study (!) of only 12 months duration
• Mean age 6.34 years (SD 0.48)
• Interesting and practicable interventions
• “Myopic” shift 0.35D (Intervention) vs. 0.47D (control) p=0.002
• Axial length grow 0.28mm (Intervention= 0.84D ) vs. 0.33mm
(control= 0.99D ) p=0.003
• Overlap of interventions turns study results questionable

HUMANS !
Environment and humans !• “Increased time outdoors is effective in preventing
the onset of myopia as well as in slowing down the
myopic shift in refractive error. But paradoxically,
outdoor time was not effective in slowing
progression in eyes that were already myopic.” (Xiong et al.: Meta-Analyse/Review, Acta Ophthalmologica 2017)

What we learned so farMyopia progression is :
• Multifactorial and strong related to age
• Potentially pathological for growing eyeballs
• Evidence based and clinically proven efficient
strategies/therapies exist
• Sunlight works mainly during emmetropization phase, very
weak correlation for inhibition in already myopic eyes
• Optimal sunlight/outdoors hours from 8 to 14
• Smart phones are less a risk
• Combination of low dose Atropine and CL works the best
Conclusion / Take Home• Act EARLY / young and consequent !
• Inform child and parents neutral and evidence based
• Choose the right therapy depending the age, the actual
myopia, the progression rate and the attitude of the parents
and the child.
• Adjust and combine strategies over time !
• Co-operation of Ophthalmologist and Optometrist is evident
